How do I know if my browser supports SVG 2.0?

Question

How do I know if my browser supports SVG 2.0?

(Apart from trying a feature that is supposed to work in SVG2 and realizing it\'s not working or that it works ...?)

Answer 1

According to SVG 2.0 specification it may be something like

document.implementation.hasFeature("http://www.w3.org/TR/SVG2/feature#GraphicsAttribute", 2.0)

SVG 1.1 support you can check with hasFeature call

document.implementation.hasFeature("http://www.w3.org/TR/SVG11/feature#SVG", 1.1)

EDIT: hasFeature is deprecated and removed from Web standards. It will return always true on modern browsers (DOM Spec).
